Definition

Discriminating lymphoma/leukemia from small, blue, round cell tumors or some non-sarcoma bone lesions may also be problematic correlation with the clinical and radiologic feature of the lesion, and ancillary techniques,  as immunohistochemical and molecular genetic analyses,  are useful tools to characterize  these lesions. 1   Histiocytic disorders as Langerhans cell histiocytosis and Erdheim-Chester disease and ,sometime Rosai-Dorfman disease, are caused by mutations of the MAPK pathway, most often BRAFV600E, lending to the use of targeted-therapy (MEK and BRAF inhibitors) trial.2

Hematopoietic neoplasms of bone neoplasms Genetic event(s)
Solitary plasmacytoma of bone Genetic aberrations similar to plasma cell myeloma. See WHO2017 Classification of Classification of Tumour of Haematopietic and Lymphoid Tissues
Primary non-Hodgkin lymphoma of bone 80% of the cases are diffuse large cell lympoma. See WHO2017 Classification of Tumour of Haematopietic and Lymphoid Tissues
Langerhans cell histiocytosis Activating mutation of the MAPK pathway (85%) mainly BRAF V600E (p.Val60oGlu) and MAP2K1. 2,3
Erdheim-Chester disease Activating mutation of the SGSM3 pathway, mainly BRAF V600E (~50%) 4 or ARAF,NRAS, KRAS or MAP2K1.2,5
Rosai-Dorfman disease Mutually exclusive missense mutations in NRAS, KRAS, MAP2K1,ARAF and BRAF (~49%) in sporadic form, and germline mutation in SLC29A3 and FAS. 2,6
